Detailed Description
The core of the application is to provide a log data processing method, a log data processing device, a server and a computer readable storage medium, wherein the log data writing process is firstly controlled in size, and then the archived log files are deleted according to the longest storage time and the largest log number, so that the log files are controlled in size and time, and the rolling effect of the log files is improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The application server log rolling policy in the prior art is mainly the following two ways. One is to scroll the log based on the size of the log file, set the maximum number of history log files, and delete the oldest history log file when the number of log files reaches the set maximum value. Another is to scroll the log based on time intervals and set the maximum storage time of the historical log file, and when the log file is stored for longer than the set time, the file is deleted. However, as the number of log files used by the server increases, the first technique is inconvenient for information search because the start time of each log file is uncertain, and when an application system is abnormal, a large number of logs are generated in a short time, and then a log rolling operation is continued, so that a large number of other history logs are deleted. In another log processing mode, if the historical log files are reserved according to a certain number, files exceeding the number are directly deleted, so that statistical analysis on the historical files cannot be performed any more subsequently.
Therefore, the log data processing method provided by the application controls the size of the log file to be written through the size of the log file to be written in the process of writing the log data so as to keep the size difference of each log file small, then stores the log file to be written in as an archived log file, and then deletes the archived log file through the longest storage time and the largest log number in the preset log rolling strategy instead of only depending on the storage time or the log number for management, thereby improving the effect of managing the log and enabling the log rolling operation to be more effective.
Referring to fig. 1, fig. 1 is a flowchart of a log data processing method according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, when receiving log data, writing the log data into a log file to be written;
the method comprises the steps of writing log data into a log file to be written when the log data are received. In the process of application of the server system, different log data can be generated at any time. And when the log data are generated, storing the log data in a log file to be written. Therefore, the log file to be written provided by the embodiment receives new log data at any time and stores the log data. However, in an actual application process, the size of the log data stored in each log file cannot be infinite, and needs to be controlled within a certain range, so that in the prior art, a new log file is generated and an old log file is archived through a log rolling operation.
Specifically, in this step, the method for writing the log data into the log file to be written may refer to any log data writing method provided in the prior art, and is not limited specifically herein.
S102, when the size of the log file to be written is larger than the preset size, executing log rolling operation on the log file to be written to obtain an archived log file and a new log file to be written;
on the basis of S101, this step aims to determine that a log rolling operation is performed on a log file to be written at a certain time. Specifically, in this step, the size of the log file to be written is used as a criterion for judgment, that is, whether the size of the log file to be written is larger than a preset size is judged. Further, in order to reduce performance consumption, it may be determined whether the size of the log file to be written is larger than a preset size after log data is stored each time. And when the size of the log file to be written is larger than the preset size, executing log rolling operation on the log file to be written.
Optionally, the step of performing a rolling operation on the log in the server in this step may include:
step 1, stamping a time stamp on a log file to be written and storing the log file as an archived log file;
and 2, creating a new log file to be written.
It can be seen that the present alternative scheme mainly further explains how to perform the log scrolling operation. Because the log file is continuously generated in real time in the using process of the server, if the log file is not subjected to real-time rolling operation and deleting operation, the log file not only occupies excessive storage space, but also seriously influences the effect of log search. Therefore, when managing a log file, a log scroll operation must be performed on the log file. Specifically, a time stamp is stamped on a log file meeting the log rolling requirement, that is, the time at this moment is marked in the log file, the log file is saved as an archived log file, and finally a new log file to be written is created, so that the received new log data is written into the log file to be written.
And S103, deleting all archived log files according to the longest storage time and the largest log number in a preset log rolling strategy.
On the basis of S102, this step is intended to perform deletion processing on all archived log files according to the log scroll policy. Specifically, in this step, the archived log files are simultaneously determined according to the longest storage time and the largest number of logs in the policy, so as to perform the deletion processing, instead of performing the deletion processing on the archived log files only by time or only by number in the prior art. In the embodiment, more strategy parameters and strategy adjustment ranges can be applied, and the log rolling effect is improved.
Optionally, this step may include:
step 1, judging whether the storage time of the archived log file is longer than the longest storage time or not according to the timestamp;
step 2, when the archived log file with the storage time longer than the longest storage time exists, deleting the archived log file;
step 3, when the archived log files with the storage time longer than the longest storage time do not exist, judging whether the number of all the archived log files is larger than the maximum number of the logs or not;
and 4, deleting the archived log file with the earliest time when the number of all the archived log files is larger than the maximum log number.
It can be seen that in this alternative, the determination is first made according to the timestamp and the longest storage time of the archived log files, if no archived log file reaches the longest storage time, the number of log files is determined, and when the number exceeds the number, the oldest archived log file is deleted. Therefore, the archived log files can be simultaneously controlled by storing the longest time and the number, and the log rolling effect is improved.
Optionally, this embodiment may further include:
and when the log file to be written is executed with the log rolling operation at preset time intervals, obtaining an archived log file and a new log file to be written.
Therefore, if the log file to be written does not reach the preset size, the log rolling operation can be performed through the preset time interval, and the overlarge time difference between the log data stored in the log file to be written is avoided.
In summary, in the process of writing log data, the size of the log file to be written is controlled by the size of the log file to be written first, so that the size difference of each log file is kept small, and then the log file to be written is saved as an archived log file, and then the archived log file is deleted and managed by the longest storage time and the largest log number in the preset log rolling policy, instead of being managed by only depending on the storage time or the log number, so that the effect of managing logs is improved, and the log rolling operation is more effective.
The following further describes a log data processing method provided by the present application with another specific embodiment.
In this embodiment, first, a setting operation of a log rolling policy is performed, and a time interval is as follows: t, log file size: l, maximum storage time: d, maximum number of logs: C.
the method can comprise the following steps:
step 1, starting a time interval timing task:
when the application server is started, a timing task with a time interval of T is started, rolling log operation is carried out every T time, and the longest storage time is judged.
Step 2, judging the size of the log file:
and after a log is written into the file each time, judging the size of the log file, and if the size is larger than or equal to L, performing log rolling operation.
Step 3, log scrolling:
renaming the current log file with the current time as a suffix, and creating a new log file.
Step 4, judging the longest storage time:
judging whether the storage time of history log files is longer than D, if so, deleting all expired log files; and if not, judging the maximum log number.
Step 5, judging the maximum log number:
and judging whether the number of the historical logs is larger than C or not, and if so, deleting the earliest log file.
And 6, deleting the earliest log file:
and selecting the earliest log file according to the date suffix of the history file, and deleting the log file.
And 7, deleting the expired log file:
and selecting all files with the storage time larger than D according to the date suffix of the historical files, and deleting all files.
It can be seen that, in the process of writing log data, the size of the log file to be written is controlled by the size of the log file to be written first, so that the size difference of each log file is kept small, and then the log file to be written is stored as an archived log file, and then the archived log file is deleted and managed through the longest storage time and the largest log number in the preset log rolling policy, instead of being managed only by means of the storage time or the log number, so that the effect of managing logs is improved, and the log rolling operation is more effective. That is, log scrolling is performed based on both log file size and time interval; the log rolling strategy can be configured according to the actual application scene of the application system; the log information is conveniently searched and positioned according to the date; therefore, the history records can be kept as much as possible, and the waste of disk space can be avoided.
